Answer:
From the image we have,
and
are linear pairs.
Linear Pair Theorem: If two angles form a linear pair, then they are supplementary.
therefore, by above theorem we have,
![11x-6+13y-14=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/6tzosjy8wiltzjnhzmz2f11xwe2yn89huv.png)
simplify:
![11x+13y=200^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/auy2h6kroig49o16xcqmsne8guv4lsxaz8.png)
Since, we can seen from the image we have,
![15x-8=90^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/8quiw0dkmx52ngi69bxkwec71njwhgmogo.png)
![15x=98^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/nb500vekcr8w8qvhvfkxv2rkpklb4g65kl.png)
therefore,
![x=6.534^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/xzp7w0hluerr6qy43s3c376348i4di9idk.png)
Now, putting the value of x in equation
to find for y:
![11\cdot 6.534+13y=200^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/z9glqbt84uajvsbyl0sqeq6s6zg4dppvfj.png)
![71.8667+13y=200^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/z6sr5k3yefcl99azrdfdxl5zegybi6auxo.png)
![13y=200-71.867=128.134^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/o0y7aleazxguhrhvcyvqjtvsbx8iazfu21.png)
Therefore the values of
and
![y=128.134^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/341wev521qhq8zc3jy9frs1ao69i7yrt5t.png)
